The city of Atlanta is growing at a rate of 2.04% each year. The 2019 population of Atlanta is 486,290 people.

What would be the Each year would it be 1 or 365?

Answers

Answer:

1

Step-by-step explanation:

The "each year" would be represented as a 1. Using the number 365 would represent the days in a year but not the entire year as a whole. For example, if we were to apply the 2.04% population increase to the population of 486,290 then that would give us the new population for the year 2020 which is 1 year more than 2019.

A wall is 22 feet tall. A ladder is leaned against that wall. The top of the ladder touches the top of the wall and the bottom of the ladder rests on the ground 8 feet from the base of wall. What is the length of the ladder?

Answers

Answer:

23.41 feet

Step-by-step explanation:

The ladder forms a right angle triangle with the wall

Height of the wall (opposite) = 22 feet

Bottom of the ladder from the wall (adjacent) = 8 feet

What is the length of the ladder?

Length of the ladder (hypotenuse)

Using Pythagoras theorem

Hypotenuse ² = opposite ² + adjacent ²

= 22² + 8²

= 484 + 64

= 548

Hypotenuse ² = 548

Hypotenuse = √548

= 23.41 feet

The length of the ladder is 23.41 feet

The design plans for a new concert hall shows elevations relative to the ground level at 0 feet. The elevation of the balcony is 37 feet and the elevation of the basement floor is -17 feet. Full in the blanks to write the distance of the balcony and basement from ground level

Answers

Answer:

54 feet

Step-by-step explanation:

The distance from the balcony to the ground level = 37 - 0 = 37ft

The distance from the basement floor to the ground level = 0 - (-17) = 17 feet

the distance of the balcony and basement from ground level will be the sum of the distances gotten = 37 - (-17)

= 37 + 17

= 54 feet

Hence the distance of the balcony and basement from ground level is 54 feet

The European Working Time Directive (EWTD) directs that staff should work no more than an average of 48 hours a week, over a 13-week period. You work from 9:00 - 18:45 with a 30 minutes lunch break for three days a week and from 10:30 - 21:00 two days a week with a 45 minutes break. You also work from 10:00 – 14:00 every second Sunday. Are your hours EWTD compliant?

Answers

Answer:

it is not EWTD compliant

Step-by-step explanation:

Given that :

Directive = maximum average working hours per week = 48 hours

Engagement :

9:00 - 18:45 = (9 hrs 45 mins) - 30 mins = 9hrs 15 mins

9 hrs 15 mins for 3 days = 27 hours 45 mins

10:30 - 21:00 = (10 hrs 30 mins) - 45 mins = 9 hrs 45 minutes

Sundays (10:00 - 14:00) = 4 hours

Total work hours per week :

2(9hrs 15 mins) + 3(9hrs 45 mins) + 4 hours =;

18 hrs 30 mins + 29 hrs 15 minutes + 4 hours

(18 + 29 + 4) + 45 minutes

51 hours 45 minutes.

51 hours 45 minutes > 48 hours ; a Hence, it is not EWTD compliant

The sequence 0, 10, 18, 25, 33, ... is not an arithmetic sequence. Then the correct option is B.

What is an arithmetic sequence?

In a Number-crunching Succession, the distinction between one term and the following is steady. Let a₁ be the first term and d be a common difference.

Then the nth term of the arithmetic sequence is given as,

aₙ = a₁ + (n - 1)d

The sequence is given below.

0, 10, 18, 25, 33, ...

The difference between two successive terms is given as,

⇒ 33 - 25

⇒ 8

⇒ 25 - 18

⇒ 7

The common difference is not the same.

Thus, the given sequence is not an arithmetic sequence. Then the correct option is B.
